I'll give the idea of the bike tubing out,
that's strange do you know what the stall current of your servos are? but its no real pro blame I've just
increased my power supply
i changed the connections to the servos and they back gripper still doesn't hold the cube I'm a little lost about because the down claw holds the cube beautifully, but i did find that by prints aren't quite aligned so
i will need to upload a different frame for those that would like to use it.
